WEATHER-STRIP FOB WINDOWS.

SPECIFICATION forming part of Letters Patent No. '7 55,552, dated March22, 1904.

Application filed May 2, 1903. Serial No. 155,354. (No model.)

To all 7/ 7L0772/ it 72m concern:

Be itknown that I, JAMES T. RoBER'rs, a citizen of the United States,residing at Claremont, in the county of Kit Carson and State ofColorado, have invented new and useful Improvements in Weather-Stripsfor Windows, of which the following is a specification.

This invention relates to a storm and dust proof attachment for windowsand the like; and the object of the invention is to interpose betweenthe edges of a sash and contiguous portion of a window-frame a metallicstrip of a particular form to prevent dust, snow, and the like frompassing between the sash and the frame and also obstruct vibration of asash during a Windstorm and obvious disagreeable noises incident to suchvibration.

The improved attachment is of such construction that it can be appliedto the side stiles, as well as the upper and lower rails, of a sash,particularly the top rail of an upper sash and the bottom rail of alower sash.

The invention consists of a metallic strip bent into elongated-U-shapedform and seated in a groove in either the sash stile or rail with thefree ends outermost to engage the windowframe and held against thelatter by fastenings passed through the center of the bend of the strip,between the opposite flanges or side members thereof, to hold the edgesof said flanges or members tightly against the window-frame, and therebyproviding means for securely fastening the attachment in place by asimple operation.

In the drawings, Figure 1 is a perspective view of a portion of awindow-frame and part of a sash, showing the improved attachment appliedthereto. Fig. 2 is a horizontal section through the sash andwindow-frame as shown by Fig. l and illustrating the shape oftheattachment and the mode of securing the same. Fig. 3 is alongitudinal vertical section of a portion of the attachment.

Similar numerals of reference are employed to indicate correspondingparts in the views.

The numeral 1 designates a window-frame having the usual stops 2,between which a sash 3 has vertical movement. As before indicated, thetop rail of the upper sash and the bottom rail of the lower sash may becaused to operate with the attachment; but instead of sliding lengthwiseover the attachment, as will be obvious, the said rails are caused tofit over the same, and under all conditions the rails and side stiles ofthe sashes are formed with deep grooves 4 of elongated-U shaped form, asclearly shown by Fig. 2. Se cured to either the side or the top andbottom portions of the window-frame is a metallic strip 5, bentintoelongated-U-shaped form and adapted to. snugly fit in the groove 4,whether it be in the side stile or in the top rail of the upper sash orbottom rail of the lower sash. The edges 6 of the opposite side membersor flanges of the strip are parallel and are placed firmly against thewindow-frame, and the attachment is secured firmly in place by drivingnails or analogous fastenings 7 through openings 8 at regular intervalsin the center of the bend 9 of the strip. The nails or other fastenings7 are caused to penetrate the Wood of the window-frame, as shown by Fig.2, and the attachment is firmly held in applied position by insertingthe nails or fastenings 7 as set forth in view of the fact that bothedges 6 are held in firm contact with the windowframe, and thereforebending of the terminals of the flanges or side members of the strip toreceive fastenings is avoided and a less number of nails or otheranalogous devices are required to attain the result sought. Moreover, byhaving the nails or other fastenings 7 passing through the center of themetal strip at regular intervals said strip is braced and prevented fromwarping or bending. Furthermore, by holding the edges 6 in firm contactwith the window-frame and having two such points of bearing dust, snow,rain, and air will be prevented from passing between the sash and theframe. Furthermore, the sash will be held in immovable position so faras vibration or rattling is concerned, yet unrestricted in its verticalmovement when it is desired to raise or lower the same. The stops 2, setforth simply as a matter of illustration, need not necessarily be used,and, in fact, said stops in ordinary window structures will be entirelyremoved, because the attachment establishes a guide to maintain the sashin proper position in the frame. By dispensing with the use of the stopsnow commonly employed in window-frames the expense of window-framestructure will be materially reduced. Where sash weights are used, theattachment will be disposed to one side of the center, so as not tointerfere with the application of the cord attached to the weight.

The attachment can also be applied to windows of houses already built orapplied where it would be difficult to plow the jamb or frame for theapplication of wood strips, and by forming the attachment of metal ithas a very great advantage over wood in that it will not swell or shrinkand is much more easily adjusted.

It is obvious that changes in the porportions, dimensions, and minordetails may be resorted to without departing from the spirit of theinvention.

Having thus fully described the invention, what is claimed as new is Thecombination with a windowsash,having a U-shaped groove opening throughthe outer edge of the side portion thereof and a frame having a guidedefined therein for removably receiving the grooved side portion of thesash, of an elongated-U-shaped metal strip extending fully throughoutthe vertical length of the center of the guide in the frame and havingthe extremities thereof straight and bearing against the frame, theinward extent of the strip being equal to the groove in the side por--tion of the sash and said strip fully inclosed by the sash, andfastening devices driven at intervals through the center of the arch ofthe strip into the frame, the hollow part of the strip having portionsof the fastening devices exposed therein to provide intermediate bracingmeans which prevents loose movement in inward and outward direction ofthe said strip. In testimony whereof I affix my signature in presence oftwo witnesses.

JAMES T. ROBERTS.
